But the drying time is basically 12-20 h, and the method has the advantages of long relative drying time, high cost, high energy consumption, slow drying rate and small treatment capacity. Microwave drying, which is a totally different method of internal heating. The wet material is in a microwave high-frequency electric field with extremely short oscillation period, water molecules in the wet material are polarized and are regularly arranged along the direction of the microwave electric field, then the wet material rapidly rotates along with the interactive change of the direction of the high-frequency alternating electric field, and violent collision and friction (hundreds of millions of times per second) are generated, so that a part of microwave energy is converted into molecular motion energy and is expressed in the form of heat, the temperature of water is increased to leave the material, and the material is dried. That is, after the microwaves enter the material and are absorbed, their energy is converted into heat energy inside the dielectric of the material. Therefore, the microwave drying is a drying mode which uses electromagnetic waves as a heating source and the dried material is a heating body.

The device further comprises two pressing rollers 42, resistance increasing rings 43 which are sleeved at two ends of the roller body 13 and are located below the two pressing rollers in a one-to-one correspondence mode, and a pressing roller lifting mechanism 44 which drives the two pressing rollers to descend so that the two pressing rollers are matched with the two pressing rollers in a one-to-one correspondence mode to clamp two side edges of the conveying belt 2. The pressing wheel lifting mechanism is a cylinder. The two lifting mechanisms of the pressing wheels are connected to the beam 45.
The second motor drives the conveying belt chamber, the clutch connects a power output shaft of the second driving motor with the second spindle head, and the two pressing wheel lifting mechanisms drive the two pressing rollers to descend, so that the two pressing wheels are matched with the two pressing rollers one to clamp edges on two sides of the conveying belt 2. When the transmission belt 2 is driven by the first driving motor, the clutch is disengaged, and the two pressing rollers are driven by the pressing wheel lifting mechanism to ascend, so that the pressing action on the transmission belt 2 is lost under the pressing rollers.
